520 _ _ |a A metal-supported SOFC (MSC) has been developed with the aim of an application in an auxiliary power unit (APU) for mobile systems. This cell design is expected to be more robust towards thermo-, mechanical- and chemical stresses that arise during operation of the SOFC-system when compared to the state-of-the-art anode supported cells (ASC). One of the most important cell-degradation pathways is the (partial) oxidation of the anode, due to oxygen diffusion into the fuel side of the stack during system shutdown. The oxidation of the nickel catalyst leads to an expansion of the anode and strain is induced within the cell, which results in microstructural degradation if a critical degree of oxidation is exceeded. We exposed MSC-halfcells to cyclic oxidation conditions by introducing air to the fuel side electrode followed by subsequent reduction in Ar/H2(4%). A detailed microstructural analysis of these samples is presented. Due to the novel MSC-concept, a higher critical degree of oxidation of nickel is tolerated before irreversible damage and cell failure are observed.
